Abstract Photovoltaic-driven Air Conditioning systems (PVAC) use local electricity generated
by distributed Photovoltaic (PV) to drive Air Conditioners (AC). Both the AC cooling load and …

In this work, numerical modeling techniques were used to determine the thermo-hydraulic
flow behavior, heat transfer enhancement, and overall thermal performance of fluid moving …

Implementation of vapor-liquid separation during condensation enhances heat transfer and
reduces pressure drop. Multi-pass-orifice header as a liquid-separation unit has been widely …

A numerical simulation on the heat transport augmentation and flow drag behavior of spirally
corrugated pipes was performed. The simulation was conducted on the basis of the …

Flooding may take place for in-tube condensation, causing unstable flow and deteriorated
heat transfer. Here, the phase separation principle is proposed to eliminate flooding …

The novel alternatively-laminated-microchannel-tube (ALMT) heat exchanger contains two
pairs of vertical headers and alternatively laminated microchannel flat tubes, which realizes …

The Micro-channel heat exchangers (MCHXs) suffer from the non-uniform distribution of two-
phase refrigerant due to the combined effects of inlet phase separation and differences in …

Vapor-liquid separation during condensation enables the enhancement of heat transfer
coefficient and reduction in pressure drop simultaneously. The vapor-liquid separator is vital …
